Led Black Light Bar, 10W 1ft USB UV Blacklight Tube, Glow in The Dark Party Supplies for Halloween Decorations, Room, Body Paint, Poster, Urine Detection, 2 Pack

Works great! I use it for lighting up a collection of Vaseline glass. The uranium in the green glass reacts with the black light to produce the MOST amazing glow. I got the idea from a display at an antique store and have been looking ever since for a small black light. I hooked it up to a cheap power bank that I tucked out of sight in the cabinet that the glass is displayed in. It's quite the conversation piece. Would also be great for Halloween decoration.

I bought these for bleaching yellowed plastic soaking in peroxide to restore it. (UV light activates peroxide and bleach.) They work surprisingly well. I imagine they would also work just fine for UV resin. I didn't think LED lights would have enough energy but they sure do. I did experience the light shutting off problem people have talked about and I think if it's not related to the light it's the power adapter getting too hot that does it. It doesn't come with the power adapters so you have to use a standard phone charger USB power plug of which I have many. I used 5V 1A plugs hoping the amps were low enough but after like 90 minutes one of them would shut off. So I just turned them off for literally one minute and turned it back on and they were fine. They are lightweight, like that lightweight model plastic so they feel fragile and the only downside is they don't come with plugs for the wall, which is fine since I have many and they are literally available for a $1 at any drug store. They work great so far. The lights themselves you can feel heat coming from but not much, just your power adapter needs to be able to handle them.

These are great. I use one in my car the other in my bedroom on posters. Super easy install, super bright, work great!

it works and is easy to hang because it's light, but it feels really cheap and dainty in my hands, one of the lights is flickering after only a little bit of use. if i drop it from 4 feet i feel like it would break apart. GET MULTIPLE SETS TO FILL UP A ROOM, they're not weak, but they're not super strong either. I did get what I paid for-----, but in hindsight I would spend a little more on a better light or stock up and buy more of these. Buy for: party, celebration, kids room, Halloween, Don't buy for : permanent installations, big rooms, long term projects.

Used this for an activity with hand washing

Plug in ports felt a little loose/wobbly, but cord stayed in fine and didn't fall out. They do feel cheap. One bar lost brightness after the first few uses, color also faded in the same bar, more of a pale purple/whitish color.. other bar still is bright and color is strong.

definitely worth the money, it's strong enough for 1 probably even two tapestries. I have both light bars on about 2 to 4 feet away .. would buy again

Not very bright, however easy to use and work.

I bought these urgently and i needed a pair. Item arrived on the same day, and worked well. I gave 4 star because it will be great if its chargeable, but nevermind. At this price, i must lower my ecpectations. Overall, i am happy with the product and fast delivery. Thank you seller! and Amazon!

Compré las lámparas para unas trampas de insectos, funcionan muy bien ambas y es posible hacerlas funcionar con una batería recargable.

Ich hab 2 von den Schwarzlicht LED Röhren in meiner Vitrine verbaut. Das Licht ist vollkommen ausreichend. Achtung wegen dem Anschluss. Es gibt keinen Stromstecker für die Steckdose sondern 2 USB Anschlüsse weswegen man noch einen USB Steckdosen Adapter braucht.- je nach Anwendungsfall.

It's really good quality.

These are great! Work well.
